Note: Unless otherwise specified, the "**kW" described in this manual refers to
the power of the G-type models. For VFDs of 75, 132, and 500 kW, G-type and
P-type models must be distinguished.
Do not refit the VFD unless authorized; otherwise, fire, electric shock or other
injuries may occur.
The base of the radiator may become hot during running. Do not touch to avoid
hurt.
The electrical parts and components inside the VFD are electrostatic. Take
measures to prevent electrostatic discharge during related operation.
1.4.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the optional braking parts (braking resistors, braking units or feedback
units) according to the wiring diagram.
Do not operate on a damaged or incomplete VFD.
Do not touch the VFD with wet items or body parts; otherwise, electric shock
may occur.
Solid State motor overload protection reacts when reaches 150% of FLA.

Note:
Select appropriate tools for delivery and installation to ensure a safe and proper running of the
VFD and avoid physical injury or death. To ensure physical safety, the installation staff should
take mechanical protective measures like wearing exposure shoes and working uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its front cover only as the cover may fall off.
Installation site should be away from children and other public places.
The VFD should be used in proper environment (see section 4.2.1 Installation environment for
details).
Prevent the screws, cables and other conductive parts from falling into the VFD,
As leakage current of the VFD during running may exceed 3.5mA, ground properly and ensure
the grounding resistance is less than 10Ω. The conductivity of PE grounding conductor is the
same with that of the phase conductor (with the same cross sectional area). For models higher
than 30 kW, the cross sectional area of the PE grounding conductor can be slightly less than the
recommended area.
R, S and T are the power input terminals, and U, V and W are output motor terminals. Connect
the input power cables and motor cables properly; otherwise, damage to the VFD may occur.
1.4.2 Commissioning and running
Disconnect all power sources applied to the VFD before terminal wiring, and wait
for at least the time designated on the VFD after disconnecting the power
sources.
High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setting. The control
terminals of VFD form extra-low voltage circuits. Therefore, you need to prevent
the control terminals from connecting to accessible terminals of other devices.
The VFD may start up by itself when P01.21 (restart after power down) is set to 1.
Do not get close to the VFD and motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot act as an emergency brake for the motor; it is a must to install
mechanical braking device.
During driving permanent magnet synchronous motor, besides above-mentioned
items, the following work must be done before installation and maintenance.
1. Disconnect all the input power sources including main power and control
power.
2. Ensure the permanent-magnet synchronous motor has been stopped, and
the voltage on output end of the VFD is lower than 36V.
3. After the permanent-magnet synchronous motor is stopped, wait for at least
the time designated on the VFD, and ensure the voltage between "+" and "-"
is lower than 36V.
4. During operation, it is a must to ensure the permanent-magnet synchronous

card units) inside the packing box are complete. If not, contact local dealers or INVT offices.
2.3 Application confirmation
Check the following items before operating on the VFD.
1. Verify the load mechanical type to be driven by the VFD, and check whether overload
occurred to the VFD during actual application, or whether the VFD power class needs to be
enlarged?
2. Check whether the actual running current of load motor is less than rated VFD current.
3. Check whether the control precision required by actual load is the same with the control
precision provided by the VFD.
4. Check whether the grid voltage is consistent with rated VFD voltage.
5. Check whether the functions required need an optional expansion card to be realized.
2.4 Environment confirmation
Check the following items before use.
1. Check whether the ambient temperature of the VFD during actual application exceeds
40°C, if yes, derate 1% for every additional 1°C (for details, see section B.2.2 Derating). In
addition, do not use the VFD when the ambient temperature exceeds 50°C .
Note: For cabinet-type VFD, its ambient temperature is the air temperature inside the
cabinet.
2. Check whether ambient temperature of the VFD during actual application is below -10°C , if
yes, install heating facility.

Note: For cabinet-type VFD, its ambient temperature is the air temperature inside the
cabinet.
3. Check whether the altitude of the application site exceeds 1000m. If yes, derate 1% for
every increase of 100m; when the installation site altitude exceeds 3000m, consult the local
INVT dealer or office.
4. Check whether the humidity of application site exceeds 90%, if yes, check whether
condensation occurred, if condensation does exist, take additional protective measures.
5. Check whether there is direct sunlight or animal intrusion in the application site, if yes, take
additional protective measures.
6. Check whether there is dust, explosive or combustible gases in the application site, if yes,
take additional protective measures.
2.5 Installation confirmation
After the VFD is installed properly, check the installation condition of the VFD.
1. Check whether the input power cable and current-carrying capacity of the motor cable fulfill
actual load requirements.
2. Check whether peripheral accessories (including input reactors, input filters, output
reactors, output filters, DC reactors, braking units and braking resistors) of the VFD are of
correct type and installed properly; check whether the installation cables fulfill requirements
on current-carrying capacity.
3. Check whether the VFD is installed on fire-retardant materials; check whether the hot parts
(such as reactors and braking resistors) are kept away from combustible materials.
4. Check whether all the control cables are routed separately with power cables based on
EMC requirement.
5. Check whether all the grounding systems are grounded properly according to VFD
requirements.
6. Check whether installation spacing of the VFD complies with the requirements in operation
manual.
7. Check whether installation mode of the VFD complies with the requirements in operation
manual. Vertical installation should be adopted whenever possible.
8. Check whether external connecting terminals of the VFD are firm and tight enough, and
whether the moment is up to the requirement.
9. Check whether there are redundant screws, cables or other conductive objects inside the
VFD, if yes, take them out.
2.6 Basic commissioning
Carry out basic commissioning according to the following procedures before operating on the VFD.
1. Select motor type, set motor parameters and select VFD control mode according to actual
motor parameters.
2. Whether autotuning is needed? If possible, disconnect the motor load to carry out dynamic
parameter autotuning; if the load cannot be disconnected, perform static autotuning.

3. Adjust the acceleration and deceleration time based on actual working conditions of the
load.
4. Jogging to carry out device commissioning. Check whether the motor running direction is
consistent with the direction required, if no, it is recommended to change the motor running
direction by exchanging the motor wiring of any two phases.
5. Set all the control parameters, and carry out actual operation.

3 Product overview
3.1 What this chapter contains
This chapter mainly introduces the operation principles, product features, layouts, nameplates and
model instructions.
3.2 Basic principle
Goodrive350-UL series VFD is used to control asynchronous AC induction motor and
permanent-magnet synchronous motor. The figure below shows the main circuit diagram of the VFD.
The rectifier converts 3PH AC voltage into DC voltage, and the capacitor bank of the intermediate
circuit stabilizes the DC voltage. The inverter converts DC voltage into the AC voltage used by AC
motor. When the circuit voltage exceeds the maximum limit value, external braking resistor will be
connected to intermediate DC circuit to consume the feedback energy.
